Correcher, VGarcia-Guinea, JMartin-Fernandez, CCan, N2024-07-182024-07-180038-7010http://akademikarsiv.cbu.edu.tr:4000/handle/123456789/8594The authors report about the influence of temperature on the thermoluminescence (TL) and cathodoluminescence (CL) behavior of a well-characterized topaz from Badajoz, Spain. Cryogenic treatments induce drastic decrease on the CL and TL intensity over 400nm involving O-Al* intrinsic defects and iron point defects. It suggests that low-energy emissions should be more associated with point defects and low wavebands to structural or intrinsic defects in the lattice. The tests of thermal stability of the UV-blue TL signal at different temperatures (in the range of 473-673 K) seem to confirm a continuous trap distribution system.EnglishPOTASSIUM-RICH FELDSPARLUMINESCENCE PROPERTIESADULARIA FELDSPARQUARTZArticle; Proceedings Paper
